A forum for beginners and members of other Buddhist traditions to ask questions about Theravāda (The Way of the Elders). Responses require moderator approval before they are visible in order to double-check alignment to Theravāda orthodoxy.

In this sutta (AN 4.193) it is the word which Sujato translates as "aggression".

Does hate … or delusion … or aggression come up in a person for their welfare or harm?” “Harm, sir.” “An aggressive individual kills living creatures, steals, commits adultery, lies, and encourages others to do the same. Is that for their lasting harm and suffering?” “Yes, sir.”

Bhikkhu Bodhi renders it as "vehemence", saying

BHSD defines sarambha as "quarrelsomeness", and connects the word with Skt. samrambha, which SED explains as "the act of grasping or taking hold of", and gives as meanings "vehemence...impetuosity, fury, wrath against." Since the sutta speaks about sarambha occurring through body speech and mind, I settle for "vehemence".

(AN translation note 909, on the same sutta).

In the Dhammapada, we have v. 133

Speak not harshly to anyone, for those thus spoken to might retort. Indeed, angry speech hurts, and retaliation may overtake you.

Where sarambha is "harsh/angry speech". Thanissaro translates the same term here as "contentious talk".
